Tardive dyskinesia: relationship with a primary affective disorder

Area of Science:

• Neurology
• Psychiatry
• Clinical Medicine

Background:

• Tardive dyskinesia is a neurological disorder characterized by involuntary movements.
• Previous research has not extensively explored the comorbidity of primary affective disorders in tardive dyskinesia patients.
• The role of substance abuse, particularly alcohol, in the presentation of tardive dyskinesia requires further investigation.

Purpose of the Study:

• To investigate the incidence of primary affective disorders in patients diagnosed with tardive dyskinesia.
• To identify potential risk factors, such as chronic alcohol abuse and depression, associated with tardive dyskinesia.
• To inform clinical practice regarding the cautious use of certain medications in patients with these comorbidities.

Main Methods:

• Retrospective review of Mayo Clinic case histories from 1965 to 1973 for diagnoses of tardive dyskinesia or dyskinesia.
• Prospective interviews with 18 consecutive patients diagnosed with tardive dyskinesia in the Department of Psychiatry and Psychology.
• Analysis of patient histories for primary affective disorders, chronic alcohol abuse, and depressive symptoms.

Main Results:

• A high incidence of primary affective disorders was observed among patients with tardive dyskinesia.
• Four out of five male patients reported a history of chronic alcohol abuse and exhibited symptoms of depression.
• These findings suggest a significant overlap between tardive dyskinesia, affective disorders, and substance abuse.

Conclusions:

• Patients with primary affective disorders, chronic alcohol abuse, and depression require extremely careful consideration before initiating antipsychotic medications, stimulants, or diazepam.
• This study highlights the importance of a comprehensive diagnostic approach in patients presenting with tardive dyskinesia.
• Further research is warranted to elucidate the complex interplay between these conditions and treatment strategies.
